Summary

  • The 1st Joint Field Test (JFT #1) with New 16-Channel System and ParkSEIS-HMA Software (February 23, 2021)

    The 16-channel acquisition system built in January has been used for the first Joint Field Test (JFT) along with the ParkSEIS-HMA
    software package on February 23, 2021.  The test lasted about 2 minutes driving the survey vehicle about 1 km distance.  It collected
    50 TDMS files that contained fifty (50) 16-channel records per file, totalling 2500 records (measurements).  This corresponds to one
    measurement about every 0.4-m distance.   The photo below shows the real-time running of the ParkSEIS-HMA software inside the
    vehicle during the field data acquisition.

  •  Evaluation of Data From JFT #1 with ParkSEIS-HMA  

    The ParkSEIS-HMA software processed 200 records (out of 2500 total) during about 5-minute duration.  It had be to stopped while it
    was processing more records because of the concern that the acquisition system (PXI unit) might be consuming too much power.  
    Nonetheless, the program displayed results of the shear-wave velocity (Vs) (top) and thickness (bottom) of the HMA pavement as shown
    below for the number of records it processed before its termination.   

    Further evaluation of all acquired records and also the ParkSEIS-HMA software that encountered a few error messages during the test
    is currently under way.
